The FDA approved the first combination pill, Harvoni (ledipasvir and sofosbuvir), to treat chronic hepatitis C virus (HCV) genotype 1 infection. It is also the first approved regimen that does not require administration with interferon or ribavirin, two FDA-approved drugs also used to treat HCV infection.
Both drugs in Harvoni interfere with the enzymes needed by HCV to multiply, according to a FDA press release. Sofosbuvir is a previously approved HCV drug marketed under the brand name Sovaldi. Harvoni also contains a new drug called ledipasvir.
“With the development and approval of new treatments for hepatitis C virus, we are changing the treatment paradigm for Americans living with the disease,” said Edward Cox, M.D., M.P.H., director of the Office of Antimicrobial Products in the FDA’s Center for Drug Evaluation and Research. “Until last year, the only available treatments for hepatitis C virus required administration with interferon and ribavirin. Now, patients and health care professionals have multiple treatment options, including a combination pill to help simplify treatment regimens.”
Harvoni is the third drug approved by the FDA in the past year to treat chronic HCV infection. The FDA approved Olysio (simeprevir) in November 2013 and Sovaldi in December 2013. Read the full release
